sprayersa An object ot our invention is to provide a simple and eiicientportable liquid sprayer, having means for detachably connecting` thesaine to commercial liquid storage containers ot variousy sizes andcapacities, and wherein the parts 01' thesprayer are so arranged andproportioned that the intakeV olf the same will always extend to theproper depth into containers of ditferentvdepths toassure the completeremoval ot the entire contents thereof.

A more specific object of the invention is to provide a device ot thecharacter indi* cat-ed comprising a pump bari-eh a piston working in thepump barrel and a hollow piston rod having oneend connected to thepiston and the other end terminating in a spraying nozzle, together withmeans comprising a stopper acting member ot varying e diameter incross-section surrounding said barrel and adapted to be inserted in thedit- 'l'erentfsiZ-ed necks ot containers ot varying sizes for holdingthe pump barrel in proper position within the container. n

ln the drawingsforming a part of this specilication, Figure 1 is alongitudinal ver* tical sectional view of a sprayer embodying ourimprovements, showing the same 'in position within a container also insection, and Figure 2 is a longitudinal sectional view through thespraying nozzle.

ln said drawings, 10 indicates a .sheet metal container of well knownconstruction provided with a screw threaded neck 111 adapted to receivethe usual screw threaded closure cap.y

The sprayer comprises a barrel 112 having secured therein at its lowerend a reducing member 13 by soldering the same thereto or attaching thesame in any other well known manner.

A hollow reciprocating piston rod 16 is slidably mounted within thebarrel 112 and has connected thereto at its lower end by soldering thesame thereto or securing the same in any other well known manner, aconnecting lit-ting 17 having a reduced screw threaded lower end 18adapted to receive the piston member 19. The piston member 19 consists oa pair of cup-shaped washers 2O and 21 held in place against theshoulder 22 by a nut 23 screwed on to the threaded end of the iitting17. l`he litting 17 is provided with a central bore 24 to providecoinniunication between the inner portion of the hollow piston r-od 16and tlreinterior of the barrel 12. A valve seat 25 is formed at theupper end ont the bore ol the litting 17 and a ball check valvetherewith. The barrel 12 is also provided with a check valve comprisinga ball 2? ada-ptedto o o-act with the seat 28 :formed at the upper endot the tube 114.v Y i A stopper member 129 is shown ot tapering ortrusto-conical 'form and is adjustably connected Vith the barrel 112 otthe sprayer. As sho\vn,tlie barrel 112 has its upper Iend provided withexterior steep pitch screw threads 150 and has secured to the upper endlthereot a vcap having a downwardly pro gecting annular flange 136 en yI @aging with the uppermost thread of the threads and vbia-.vinga guideopening` 151 therein receiving the upper end or" the piston rod 116.

The stopper member 129 comprises an inner threaded nut member 152engaging with the threads 150 on the barrel 1127 and an outer conicalsleeve member 153 secured to the nut 152 by solder or any' other wellknown means. Securedto the upper vend of the nut 152 and sleeve 153 is adisc 154 having laterally proj ect-ing wings 155 adapted to serve aslinger rests. Y

The upper end portion 39 oi the hollow piston extends at right angles tothe major portion thereof and is connecter thereto by the curved portion48. The outer end of the tubular portion 39 is provided with a sprayingnozzle or tip 40.' The tip 40 as clearly shown on Figure 2 is providedwith interior screw threads 41 in threaded connection with a litting 42receiving the end ot thetube 39 and being secured thereto by solder orany other well known means. A plug 43 is re'- ceived within the cap 40,the former being provided with threads engaging with the threads 41 ot'the cap 40. The plug 43 is provided with oppositeiy locatedV diagonalgrooves 44 forming ports to convey the liquid from the tube 39 to thefront end of the cap to thereby produce a whirling action ot the fluidas it passes through the tip. The plug 43 is also provided with arearwardly project-ing cylindrical post 45 loosely received within theend ot the tube 39 to there- 26 is adapted to co-oper-` Cai by providean annular recess 46 to direct the liquid to the inner ends of the ports44. rllhe outer end of the cap 40 is provided with a small perforation47 through which the liquid is sprayed; p y

In'operation the device is adapted to be inserted in the vessel110, theconical stopper 129 being fitted within the mouth 132 of the neck 111 ofsaid receptacle. Should the 'lower end of the tube 114 not extend to theproper depth-into the vessel to assure the removal of the entirecontents', the barrel 112 may be rotated within the nut`152 thusadjusting the sleevev 'downwardly toward the bottom of the vessel; ltwill be evident that due to the conical construction of the stopper 129,

the Vsaine is adapted to 4lit the various sizes of mouths of differentcapacityV containers, and that due to the screw threaded adgustmentprovided between the stopper 129 and Y the barrel 112, the barrel 112together with the tube 114. may be adjusted to correspond to the varyingdepth of vessels of different capacity and size. lllhe finger rests 155are then engaged by the operator and the piston 16 is i'eciprocated.Upon upward movement of the piston rod 16, liquid will be drawn upwardlythrough the tube 114 into the barrel 112 of the sprayer. During thisupward movement of the piston it is obvious that the valve 26 will beclosed while the valve 28 will be open to admit, the fluid. Upon thenent downward stroke of the piston rod 16, the valve 28 will be closedand the valve 2G will be forced open due to the upward pressure yof theliquid, andthe liquid forced through the hollow piston rod 16. Duringsuccessive reciprocations of the piston rod 16, the liquid will beforced through the hollow piston rod past the plug 43, a whirling motionbeing imparted to the same by passage through the ports 44, and willfinally be sprayed through the small opening' 47 in the cap 40.

Vie have herein shown and described what we now consider the preferredmanner of carrying out the invention, but the saine is by way ofdescription only, and not by way of limitation. All changes andmodifications are contemplated that come within the scope of the claimsappended hereto.

barrel and terminating with a spray nozzle,

and the said piston rod being formed outwardly of the pump barrel, toprovide a hand grasp for reciprocation; intake and outlet valvesassociated with said pump barrel and piston; a plug` adjustably threaded4on the exterior of said pump barrela said plug being exteriorly formedto adapt it for co-opeiation with the discharge openings of varyingdiameters of the containers; and finger nieces located adjacent saidplug and extending' laterally of the sprayer whereby the spray-er may beheld in proper position in the container by said finger pieces by onehand of the operator and the piston and pisn ton rod operated by theother hand of the operator.

2. In a spraying device, the combination with a pump barrel adapted tobe inserted into containers having various sized orifices, and ofvarious capacities; of means for supporting said barrel in a container,said supporting means having a graduated 4contour whereby orifices ofdifferent sizes may be snugly engaged; and means connecting said barreland supporting means whereby rotation of said barrel relative to saidsupporting means effects longitudinal movement of said barrel withrespect to said container for ati- ]'usting the barrel in containers ofvarying capacity while in operativo position.

1nV witness that we claim the foregoing we have hereunto subscribed ournames, this 31st day of October A. D. 1922.
